Question

Area of rectangle is 192 cm²& its breath is 12 cm. Find the perimeter and the diagonal of the rectangle.​

Answer 1

Answer:

Perimeter = 56 cm        Diagonal = 20 cm

Step-by-step explanation:

Area = length x breadth

Breadth = area/length

192/12 = 16 cm

(12x2) + (16x2) = perimeter

= 56 cm

We can then use the Pythagorean Theorem to find the diagonal.

Diagonal = $\sqrt{length^2+width^2}$

Diagonal = $\sqrt{12^2+16^2}$

$12^{2} = 144$               $16^{2} = 256$

144 + 256 = 400

$\sqrt{400} = 20$
