Question

calculating the area of rhombus
The area of field shaped in trapezium is 1400sq. dem. Ir the perpendicular distance between
two parallel sides are 20dem and the length of two parallel sides are in the ratio 3:4, then let
us write by calculating the lengths of two sides​

Answer 1

Answer:

Given that,

Area of trapezium field = 1440 m2

Height of field = 24 cm

Ratio of parallel sides 5 : 3

Let the sides be 5x and 3x.

We know that,

Area of trapezium = 21 (Surn of parallel side) × Height

1440 = 21 (5x + 3x) × 24 ⇒241440×2 = (5x + 3x)

120 = 8x ⇒ = 15

Hence, longer side =  5 × 15 = 75 cm
