Question

A rectangular pizza is cut into 4 triangles as shown. Find the sum of the areas of the 4 triangles.

• A. 200 square units
• B. 250 square units
• C. 275 square units
• D. 300 square units

Answer 1

The correct option is D 300 square units

$AreaofTriangle1=\frac{1}{2}\times Base\times Height$
$=\frac{1}{2}\times 12\times 12.5=75squareinches$

Area of Triangle 2
$=\frac{1}{2}\times 25\times 6=75squareinches$

Area of Triangle 1 = Area of Triangle 3 = 75 square inches

Area of Triangle 2 = Area of Triangle 4 = 75 square inches

Area of Triangle 1 + Area of Triangle 2 + Area of Triangle 3 + Area of Triangle 4
= 75 + 75 + 75 + 75
= 300 square units
