Question

I need help with this problem please.

Answer 1

1725 sq.ft

Explanation:

Given

Parallel sides of the trapeziod yard = 50ft , 65ft

Height of the trapezoid = 30ft

Therefore, area of the trapezoid yard

`= (b1 + b2)/(2) * h`

`= (50ft + 65ft)/(2) * 30ft`

`= (115ft)/(2) * 30ft`

= 57.5 ft × 30 ft

`= 1725 {ft}^(2) (ans)`

Answer 2

1725ft^2

Explanation:

Area of trapezoid:

`(b_1+b_2)/(2)*h`

Substitute the values and solve:

`(50+65)/(2)*30=1725`ft^2
