Hep me on this please

Alona [7]

Answer:

The answer is 2240m².

Step-by-step 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 :

$area = \frac{1}{2} \times (a + b) \times h$

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

$area = \frac{1}{2} \times (50 + 90) \times 32$

$area = \frac{1}{2} \times 140 \times 32$

$area = 70 \times 32$

$area = 2240 \: {m}^{2}$
