The length and width of a rectangle are in the ratio 3:2 .If the perimeter is 100 cm, what is the area of the rectangle

600 cm²

Step-by-step explanation:

We know that:

Solution:

Hoped this helped!

First of all We will find the length and breadth with the help of perimeter and then find the area...

Ratio of length to breadth is 3:2, So let length be 3x and breadth be 2x

ATQ,

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
