Question

Shirley buys a piece of remnant fabric that is triangular in shape with a base length of 2 yd and a height measuring one half yd. If the fabric sells for $4.50 per square yard, how much does Shirley pay for the piece of fabric?

Answer 1

the 2 x 0.5 triangle fabric piece cost $2.25

Explanation:

• Area of a triangle = 1/2 x base x height
• base: 2 yards
• height: 0.5 yards
• Area of fabric: 1/2 x 2 x 0.5 = 0.5 yards squared

• Price per square yard: $4.50
• Actual price: $4.50 / 2 = $2.25
