Question

The area of trapezium is 176cm^ .the distance between parallel sides is 8cm and one of the parallel sides is 10 cm .find the answers
$area of trapezium 1\2 (a + b)$
176 = 1/2(a+b) × 8
176 = 4(a+10)
4a = 176 - 40 = 136
a = 136/4 = 34cm
thus, the length of other side = 34
​

Answer 1

1/2*8* (10+b)=17
40+4b=176
B=34
