Arte-miy333 [17]

Answer: The height of wall is 10.5 feet.

Step-by-step explanation:

Since we have given that

Number of bricks to build = 1470

Length of wall = 20 feet

We need to find the height of wall.

As we know that

Bricklayer's formula is given by

$N=7LH\\\\1470=7\times 20\times H\\\\1470=140\times H\\\\\dfrac{1470}{140}=H\\\\10.5\ ft=H$

Hence, the height of wall is 10.5 feet.

The backyard is 20 inches long and 37 inches wide. What is the area of the backyard?

$\diamond\large\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}$

We are given the backyard's length (20 inches long) and the backyard's width (37 inches wide).

We are asked to find the area of the backyard, which can be found using the following formula:-

$\boxed{\bold{A_{(rectangle)}=LW}}$

<u>Where:-</u>

<u></u>

A=Area of rectangle
L=Length (20 inches)
W=Width (37 inches)

Substitute the values:-

$\boxed{\bold{A=20*37}}$

On simplification,

✳︎ $\boxed{\bold{A=740\:in^2}}$ , which is our final answer.

<h3> Good luck with your studies.</h3>
