Given : Perimeter of a trapezium is 152 m Non-parallel sides of a trapezium are 18 m and 24 m Height of a trapezium = 12 m To Find : Area of trapezium. Calculations : Firstly let’s calculate the length of non-parallel sides of a trapezium, [tex] \mapsto \sf 18 + 24 \: m [/tex] On adding the numbers, [tex] \mapsto \rm{ \green{42 \: m}} [/tex] So, length of non-parallel sides of a trapezium is 42 m. Now, let’s calculate the length of non-parallel sides, so in order to calculate non-parallel sides, we need to perform subtraction in :- Perimeter of trapezium (152 m) – total length of parallel sides (42 m) So, let’s find the length parallel sides of a trapezium, [tex] \mapsto \sf 152 \: m – 42 \: m [/tex] On subtracting the numbers, [tex] \mapsto \rm{ \green{110 \: m}} [/tex] So, the length of parallel sides of a trapezium is 110 m. According to the Question, Now, let’s calculate the area of trapezium, In order to find the area of trapezium, Formula to be used : [tex] \boxed{\rm{ \pink{{Area_{(Trapezium)} = \dfrac{1}{2} \times Sum \: of \: parallel \: sides \times height}}}} [/tex] [tex] \dag [/tex] Putting the values, [tex] \mapsto \sf Area_{(Trapezium)} = \dfrac{1}{2} \times 110 \: m \times 12 \: m \\ \\ \mapsto \sf Area_{(Trapezium)} = 55 \: m \times 12 \: m \\ \\ \mapsto \sf \boxed{ \bf{Area_{(Trapezium)} = 660 \: m^2 }} \: \pink{\bigstar} [/tex] Henceforth, Area of trapezium is 660 m².

The perimeter of a trapezium is 152m, its non-parallel sides are 18m and 24m and its altitude is 12m.
★ To find :
Find the area of trapezium.
★ Solution :
⚘Length of non Parrallel sides
➞ 18 + 24
➞ 42 cm
⚘Length of Parrallel sides
➞ 152 – 42
➞ 110 m
⚘We know that, Area of trapezium
➞ 1/2 × Sum of Parrallel sides × H
➞ 1/2 × ( 110 ) × 12
➞ 1/2 × 1320
➞ 660 m²
