Question

the area of trapezium is 360 square the distance between the two parallel sides is 20 m and the 1 parallel sides 25 metre find the other side

Answer 1

360 = 1/2 × ( 25+ x)×20
360=250 +10x
360-250 = 10x
x=11

Answer 2

Hi Friend ✋✋✋

$area \: of \: trapezium \: = \frac{1}{2} \times h \times (sum \: of \: parallel \: sides \: )$
Area = 360 m².

hieght , h = 20 m

One of the parallel side , a = 25 m

Other side be , b = ?

$360 = \frac{1}{2} \times 20 \times (25 + b) \\ \\ 360 = 10 \times (25 + b) \\ \\ 36 = 25 + b \\ \\ b = 11 \: cm$
Other side is 11 cm


Hope it helps
