Question

A square with an area of 1 square meter is decomposed into 9 identical small squares. Each small square is decomposed into two identical triangles.
1.What is the area, in square meters, of 6 triangles? If you get stuck, consider drawing a diagram.
2.How many triangles are needed to compose a region that is 1 1/2 square meters?

Answer 1

Answer:

1. 1/3 square meter

2. 99 triangles

Step-by-step explanation:

1. area of square = 1 sq.m

area of each small square =1/9 sq.m

Area of each triangle = 1/9 x 0.5 =1/18 square meter
