Answer:

Vinita is 8 years old.

Step-by-step explanation:

We know that Smita is <u>twice</u> as old as Vinita, this means Smita is 2 times the age of Vinita. We can represent this in an equation, where the age of Vinita is x.

2x is the age of Smita.

x is the age of Vinita.

The sum of their ages is 24.

so we can write this as:

2x + x = 24

2x + x is 3x so,

3x = 24

Then divide each side by 2 to get x by itself.

x = 8

Hence, Vinita is 8 years old.

$\large{\underline{\underline{\pmb{\sf {\color {blue}{Solution:}}}}}}$

Given,

Area = 225 yd²

Base = 30 yd

Height = [To be calculated]

To find:

The height of the given triangle.

We know that, area of a triangle is:

$\frac{1}{2} \times (b \times h) \\ \\ \leadsto \frac{1}{2} \times (30 \times h) \\ \\ \leadsto \frac{1}{2} \times 30h \\ \\ \leadsto \frac{1}{ \cancel{2}} \times \cancel{30}h \\ \\ \leadsto1 \times 15h \\ \\ \leadsto \: h = 15 \: yd$

Therefore, the require height is 15 yd.

$\green\star$ Proof:

$\frac{1}{2} \times (b \times h) \\ \\ \leadsto \frac{1}{2} \times (30 \times 15) \\ \\ \leadsto \frac{1}{ \cancel{2}} \times \cancel{450} \\ \\ \leadsto1 \times 225 \\ \\ area = 225 {yd}^{2}$

$\boxed{ \frak \red{brainlysamurai}}$

A can of orange juice has a circular base with an area of 156 square centimeters. The height of the can is 20 centimeters.

A Because if you do 156 x 20 it equals 3120. It’s A because the volume formula is Length x Width x height, And 156 and 20 were the only numbers given.
