A shape is made of 12 right triangles of equal size .Each right triangle has a base of 4 cm a height of 5 cm. what is the total area in square centimeters of the shape

120

Step-by-step explanation:

All you need to do is find the area of 1 triangle and multiply that area by 12.

The area of a triangle is The b is for the base and h is for the height

Lets find the area of 1 triangle:

(multiply 1/2 *4)

(multiply 2*5)

(this is the area of 1 triangle)

To find the total area of all 12 triangles multiply 10 * 12

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

the answer is 11.2 (i know i’m late)
