Step-by-step explanation:

Given

L = 8cm

W = 12cm

r = 2 -- folded twice

Required

The area of the new rectangle

When the length was folder, the new length is:

l = L/2 = 8cm/2 = 4cm

When the width was folder, the new width is:

w = W/2 = 12cm/2 = 6cm

So, the new area is:

Area =l * w

Area =4cm * 6cm

Area =24cm^2

Identify the perimeter of a rectangle in which h = 8 ft and a = 144x ft^2. please help asap
Blababa [14]

Here, Given

h= 8ft

a=144 * ft^2

then,

A=L*H

144=L*8 or 144/8 =L

L=18

now, P=2(L+H)

P=2(18+8)

P=52m

Perimeter and area are two important and basic mathematical subjects. They help quantify the physical space and also provide a more advanced foundation of mathematics in algebra, trigonometry, and calculus. Perimeter is a measure of the distance around a shape, and area indicates how much area the shape covers.

The perimeter of a 2D shape is the distance around the shape. You can imagine wrapping a string around a triangle. The length of this cord is around the triangle. Or, if you're traveling outside the park, take a route that goes around the edge of the park.
