Question

how to solve: Find a diagonal of a rectangle whose length is 35 cm and breadth is 12 cm

Answer 1

for finding
the diagonal of rectangle =square of length + square of breath
35×35+12×12 =1225+144= root 1369= 37 cm length of diagonal

Answer 2

Answer:

Diagonal of rectangle is 37 cm.

Step-by-step-explanation:

The diagonal of rectangle is like a hypotenuse.

So, by Pythagors Theorem

(Hypotenuse)² = (Length)² + (Breadth)²

=> (Diagonal)² = (35)² + (12)²

=> (Diagonal)² = 1225 + 144

=> (Diagonal)² = 1369

=> Diagonal = 37 cm

Hence,

Diagonal of rectangle is 37 cm.
