Question

7 The height of a trapezium is 7 m. One of its bases is
8 m. The area of trapezium is 154 m. Find the other
base.​

Answer 1

Answer:

36cm

Step-by-step explanation:

Area of trapezium = h(a+b)/2

   154=7(8+b)2

    44=8+b

    b=36cm

So, the lenght of other base is 36cm

Answer 2

Answer:

Given,

area of a trapezium =154m

one of its base is 8m

let the base be a=8m

another base be b =?

area of a trapezium=h/2(a+b)

154 = 7/2(8+b)

308 = 7(8+b)

308 = 56 + 7b

308 - 56 = 7b

252 = 7b

252/7 = b

b = 36m

Therefore, the other base of the trapezium b is 36m
