In the given shelf which is right angled at A, AB = AC = 48 inches. Find the area of the shelf.
1152 sq. inches
Area of a triangle = 12×base×height
Here, the given triangle is right angled at A.
Considering AB as the base and AC as the corresponding height, we get
Area of the shelf = 12×AB×AC
= 12×48×48
(Since AB = AC = 48 inches)
= 1152 sq. inches
Hence, area of the shelf is 1152 sq. inches.
