Question

Find the area of the given Christmas tree.

• A. 55 square inches
• B. 63 square inches
• C. 64 square inches
• D. 65 square inches

Answer 1

The correct option is A 55 square inches

Area of the christmas tree = Area of Triangle A + Area of Triangle B + Area of Triangle C + Area of the rectangle

$Areaofatriangle=\frac{1}{2}\times Base\times Height$
$AreaofTriangleA=\frac{1}{2}\times 3\times 4$
$=6$ square inches

$AreaofTriangleB=\frac{1}{2}\times 6\times 8$
$=12$ square inches

$AreaofTriangleC=\frac{1}{2}\times 12\times 5$
$=30$ square inches

Area of the rectangle = Length × Width
= $7\times 1$ = 7 square inches

Area of the christmas tree
= 6 + 12 + 30 + 7 = 55 square inches
