Ashape is made of 12 right triangles of equal size each right triangle has a base of 4cm and a height of 5 cm what is the total area, in a square centimeter, of the shape
a: 10
b: 60
c: 120
d: 240

120 square centimeter. (c)

Step-by-step explanation:

Total Area = 12 * area of one triangle  [area of right triangle = 1/2 * b * h]

= 12 * 1/2 * b * h

= 12 * 1/2 * 4 * 5

= 120 square centimeter.

C:120

Step-by-step explanation:

The area of each triangle is A = 1/2 bh

A = 1/2 (4)*5

A = 10 cm^2

We have 12 triangles

The total area is  12 times the area of 1 triangle

total area = 12 * A triangle

                = 12 * 10

                =120 cm^2
