Question

answer the questions below. write your answers in simplest form.
(a) a square has a perimeter of 56 cm. what is the length of each side?
\boxed{} cm
(b) a square has an area of 144 \\(\mathrm{m}^2\\). what is the length of each side?
\boxed{} m

Explanation:

Part (a)

Step1: Recall square perimeter formula

A square has 4 equal sides, so perimeter \( P = 4s \), where \( s \) is side length.

Step2: Solve for \( s \)

Given \( P = 56 \) cm, substitute into formula: \( 56 = 4s \). Divide both sides by 4: \( s=\frac{56}{4}=14 \).

Step1: Recall square area formula

Area of a square \( A = s^2 \), where \( s \) is side length.

Step2: Solve for \( s \)

Given \( A = 144 \) \( m^2 \), take square root: \( s=\sqrt{144}=12 \).

Answer:

14
