if the area of triangle ABC= 25 square feet, then the area of the rectangle ABCD is:

25 square feet.
35 square feet.
40 square feet.
50 square feet.

if the area of triangle ABC 25 square feet then the area of the rectangle ABCD is 25 square feet 35 square feet 40 square feet 50 square feet class=

Respuesta :

A rectangle has 2 triangle
∴ 25 feet² × 2 = 50 feet²
Should be 50 square feet. Area of triangle is base x height / 2 and area of rectangle is side1 x side2. In this case, base x height = 25 x 2 = 50, and base =side1 and height=side2.
