Answer 1

Answer:

B = 56 cm

Step-by-step explanation:

S of square = $\frac{P}{4}$

S = $\frac{48}{4}$

S = 12

A of square = $S^{2}$

A = $12^{2}$

A = 144 $cm^{2}$

A of rectangle = A of square - 4

A = 144 $cm^{2}$ - 4

A = 140 $cm^{2}$

B of rectangle = $\frac{P}{2} - l$

B = $\frac{140}{2} - 14 cm$

B = $70cm-14cm$

B = 56 cm
