Answer:
50.22 in²
Step-by-step explanation:
A shelf has the shape of a triangle. The base of the shelf is 36 centimeters, and the height is 18 centimeters. Find the area of the shelf in square inches. Round to the nearest hundredth.
Area of a Triangle = 1/2 × Base × Height
Base = 36 cm
Height = 18 cm
Area of the Triangle = 1/2 × 36 × 18
= 324 cm²
The area of the shelf(Triangular in shape) = 324 cm²
Converting to square inches
1 square centimetre = 0.155 square inch
324 square centimetre = x
x = 324 × 0.155 in²
x = 50.2201 in²
Approximately to the nearest hundredth = 50.22 in²
Therefore, the area of the shelf in square inches is 50.22 in²
