Answer:

875 ft²

Step-by-step explanation:

Finding area of similar rectangles:

Scale factor = EF : AB

= 25 : 5

= 5 : 1

$\sf \dfrac{Area \ of \ bigger \ rectangle}{Area \ of \ smaller \ rectangle}= (Scale \ factor)^2$

$\dfrac{Area \ of \ bigger \ rectangle}{35} =\left(\dfrac{5}{1}\right)^2$

$\text{Area of bigger rectangle = $\dfrac{25}{1}*35$}$

Area or rectangle EFGH = 875 ft²
