Question

. Find the diagonal of a rectangle whose length is 15 cm and area is 120 sq. cm.

Answer 1

Answer:

Given :-

Length of the rectangle = 15 cm

Area of a rectangle = 120 cm²

To Find :-

The perimeter of a rectangle.

Solution :-

We know that,

l = Length

b = Breadth

a = Area

p = Perimeter

Let us consider the breadth to be 'x'.

Given that,

Length (l) = 15 cm

Area (a) = 120 cm²

Substituting their values,

 the breadth of the rectangle is 8 cm.

 Given that,

Length (l) = 15 cm

Breadth (b) = 8 cm

Substituting the values,

Perimeter = 2(15 + 8)

= 2(23)

= 46 cm

Answer 2

Answer:

17 cm

Step-by-step explanation:

B/c,

B/c,B=

$\frac{120}{15}cm \\ = 8cm$

Now,

$h {}^{2} = l {}^{2} + b {}^{2} \\ = (15) {}^{2} + (8) {}^{2} \\ = \sqrt{289} \\ = 17cm$

This is the answer. Hope this helps you.
