Question

area equation:
4 × 11 = 44 square units
perimeter equation:
11 + 11 + 11 + 11 = 44 units

Explanation:

Step1: Calculate the area

The formula for the area of a rectangle is \(A = length\times width\). From the grid, the length is \(11\) units and the width is \(4\) units. So, \(4\times11 = 44\) square units.

Step2: Calculate the perimeter

The formula for the perimeter of a rectangle is \(P=2\times(length + width)\) or \(P = length+length + width+width\). Here, \(11 + 11+4 + 4=(11\times2)+(4\times2)=22 + 8=30\) units.

Answer:

Area Equation: \(4\times11 = 44\) square units; Perimeter Equation: \(11+11 + 4+4=30\) units.
