find the area of quadrilaterals when height are 1.5 cm and 2.6 cm diagonal is 5.5 cm. with full answer About the author Vivian
Area of quadrilateral ABCD= 2 1 d(h 1 +h 2 ) Sum of the length of perpendicular from the remaining two vertices on the diagonal AC=(h 1 +h 2 ) h 1 +h 2 =12cm. Length of the diagonal (BD)=11cm. ∴ Area of quadrilateral = 2 1 d(h 1 +h 2 )= 2 1 ×12×11=6×11=66 cm 2 . Reply
