Find: i) The height of a triangle whose base is 17 m and area is 340m2. ii) The base and the height of the parallelogram if, base of a parallelogram is thrice its height & its area is 192cm2. About the author Rose
Answer: 1.. 1/2×b×h = 1/2×17×h = 340m = 8.5×h = 340m = h = 340/8.5 = 40m 2.. b×h = 3x×x = 192 = 3x^2 = 192 = x^2 = 192/3 = x^2 = 64 = √x^2 = √64 = x = 8 so, b = 3x = 3×8 = 24 Reply
Answer:
1.. 1/2×b×h
= 1/2×17×h = 340m
= 8.5×h = 340m
= h = 340/8.5 = 40m
2.. b×h
= 3x×x = 192
= 3x^2 = 192
= x^2 = 192/3
= x^2 = 64
= √x^2 = √64
= x = 8
so, b = 3x = 3×8 = 24
