Question 1: Equiangular

Question 2: Area of the parallelogram = 48 square centimeters

Question 3: Perimeter of the rectangle = 42 ft

Question 4: Area of the trapezoid = 154 square inches

Solution:

Question 1:

The given polygon is a rectangle.

The angles of each side of the polygon is 90°.

This means all angles are equal.

Hence Option A equiangular is the correct answer.

Question 2:

Area of the parallelogram = Base × Height]

= 6 cm × 8 cm

Area of the parallelogram = 48 square centimeters

Question 3:

Perimeter of the rectangle = 2(length + width)

= 2( 15 ft + 6 ft)

= 2(21 ft)

Perimeter of the rectangle = 42 ft

Question 4:

Area of the trapezoid = $\frac{1}{2}\times \text{sum of the parallel sides}\times \text{height}$

$$=\frac{1}{2}\times (14+ 8)\times 14$

$$=\frac{1}{2}\times 22\times 14$

Area of the trapezoid = 154 square inches
