Question

Round your answer to the nearest whole number

Answer 1

Answer:

The area of the rectangle is 1596 inches.

Step-by-step explanation:

The diagonal cuts the rectangle in 2 congruent triangles.

Let's find the area of triangle and multiply it by 2 to get the area of rectangle.

area = (b x h) : 2  (This is the formula to find the area of triangle.)

area = (42 x 38) : 2

area = 1596 : 2

area = 798

area of rectangle = area of triangle + area of triangle

area of rectangle = 798 + 798

area of rectangle = 1596 inches
