Question

find diagonal of rectangles whose length is 35 cm 12 cm

Answer 1

a diagonal divide a rectangle in two right angle triangles..
so, by Pythagoras theorem,
${h}^{2} = {p}^{2} + {b}^{2}$
${h}^{2} \: = {35}^{2} + {12}^{2}$
${h}^{2} = 1225 + 144$
${h}^{2} = 1369$
$h = 37cm$

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.
