Question

1. what is the area of triangle a?

a. 40 square centimeters
b. 16 square centimeters
c. 20 square centimeters
d. 32 square centimeters
triangle area: ( b\times hdiv2 )

1. what is the matching base for the given height of this parallelogram?

a. 15 inches
b. 8 inches
c. 9 inches
d. 24 inches
area: 27 square inches

1. draw two different parallelograms that each have an area of 18 square units.

parallelogram 1
parallelogram 2

Explanation:

Step1: Calculate the area of triangle A

The formula for the area of a triangle is \(A=\frac{1}{2}\times b\times h\). Here, \(b = 4\) cm and \(h=8\) cm.

Step2: Find the base of the parallelogram

The formula for the area of a parallelogram is \(A = b\times h\). Given \(A = 27\) square inches and \(h = 3\) inches.

Answer:

1. B. 16 square centimeters
2. C. 9 inches
3. For parallelogram 1: base \(b = 6\) units and height \(h=3\) units (since \(A=b\times h=6\times3 = 18\)). For parallelogram 2: base \(b = 9\) units and height \(h = 2\) units (since \(A=b\times h=9\times2=18\)). (Drawings would be made on the grid paper accordingly with the calculated base and height values)
