Question

a square picture has a frame of length 100 cm what is the length of its side what is its area

Answer

Given

Length = 100cm

To Find

What is the length

Solution

Perimeter of square = 4×side

100=4×side

$\sf \cancel\frac{100}{4} = side$

25 = side

Area of square = (side)²

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \sf \ { = 25 \times 25 = 625cm {}^{2} }$

So the area of a square is 625 cm²
