Question

Hep me on this please

Answer 1

The answer is 2240m².

Explanation:

Given that the formula of area of trapezium is A = 1/2×(a+b)×h where a and b represents the length and h is height :

`area = (1)/(2) * (a + b) * h`

`let \: a = 50 \\ let \: b = 90 \\ let \: h = 32`

`area = (1)/(2) * (50 + 90) * 32`

`area = (1)/(2) * 140 * 32`

`area = 70 * 32`

`area = 2240 \: {m}^(2)`

Answer 2

2,240 square meters

Explanation:

The shape above is a trapezoid. Therefore, we can use the area formula for a trapezoid:

A=1/2(a+b) *h

where a is the short base, b is the long base is h is the height.

In this trapezoid, the short base is 50 meters , the long base is 90 meters and the height is 32 meters.

a= 50

b=90

h=32

A=1/2(50+90)*32

Add inside the parentheses first.

A=1/2(140)*32

Multiply 1/2 and 140, or divide 140 by 2.

A=70*32

Multiply 70 and 32

A=2240

Add appropriate units. In this case, the units are meters^2

A=2240 meters^2

The area of the playground is 2,240 meters^2
