Question

Find the area please

Answer 1

D 30 ft^2

Explanation:

This figure is a trapezoid

The area of a trapezoid is given by

A = 1/2 (b1+b2) *h where b1 and b2 are the lengths of the top and bottom

A = 1/2( 10+5) * 4

= 1/2 (15)*4

= 1/2(60)

= 30 ft^2

Answer 2

For this case we have that by definition, the area of a trapezoid is given by:
`A = \frac {(B + b) * h} {2}`

Where:

B: It is the major base

b: It is the minor base

h: It's the height

According to the data we have:

`B = 10ft\\b = 5ft\\h = 4ft`

Substituting:

`A = \frac {(10 + 5) * 4} {2}\\A = \frac {15 * 4} {2}\\A = \frac {60} {2}\\A = 30`

So, the area of the figure is
`30 \ ft ^ 2`
