Question

find the diagonal of a rectangle whose length is 35cm and breadth is 12cm​

Answer 1

Answer:

37 cm

Step-by-step explanation:

Using Pythagoras Theorem:-

(Diagonal)^2=(Length)^2+(Breadth)^2

Diagonal^2=35^2+12^2

Diagonal^2=1225+144

diagonal^2=1369

Diagonal=√1369

Diagonal=37 cm

Answer 2

GIVEN:

• Length of a rectangle = 35 cm
• Breadth of the rectangle = 12 cm

TO FIND:

• What is the diagonal of the rectangle ?

SOLUTION:

✎ We have given the length and breadth of a rectangle are 35 and 12 cm respectively

☞ Let the length of the diagonal be 'd'

To find the length of the diagonal of rectangle, we use the formula:-

❰ d² = l² + b² ❱

According to question:-

On putting the given values in the formula, we get

➪ d² = (35)² + (12)²

➪ d² = 1225 + 144

➪ d² = 1369

➪ d = $\sf{\sqrt{1369}}$

❮ d = 37 cm ❯

❝ Hence, the length of the diagonal of the rectangle is 37 cm ❞
