Question

Determine​ (a) the area and​ (b) the perimeter of the quadrilateral.

4in
5in
12in
5 in
and inside forms a right angle of 1/4 ft

Answer 1

The quadrilateral you're describing sounds like a rectangle because of the right angle and equal opposite sides.

(a) The area of a rectangle is found by multiplying the length by the width. So, 4in*12in = 48 square inches.

(b) The perimeter is found by adding all sides. So, 4in + 5in + 12in + 5in = 26 inches.

So, the area is 48 square inches and the perimeter is 26 inches. Geometry is quite fascinating, isn't it?
