Answer:
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
