If the length of a rectangle is 12cm and the area is 48. What's the breadth and what's the perimeter??

1. The breadth is 4 cm

2. The perimeter is 32 cm

Step-by-step explanation:

From the question given above, the following data were obtained:

Length (L) = 12 cm

Area (A) = 48 cm²

1. Determination of the breadth.

Length (L) = 12 cm

Area (A) = 48 cm²

Breadth (B) =?

A = L × B

48 = 12 × B

Divide both side by 12

B = 48 / 12

B = 4 cm

Thus, the breadth is 4 cm.

2. Determination of the perimeter

Length (L) = 12 cm

Breadth (B) = 4 cm

Perimeter (P) =?

P = 2(L + B)

P = 2(12 + 4)

P = 2(16)

P = 32 cm

Thus, the perimeter of the rectangle is 32 cm

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

he earned 78.75 in interest.
