Question

Find the area and perimeter please help me :)

Answer 1

Answer:

Perimeter: 44

Area: 96

Step-by-step explanation:

Perimeter - Just add all the sides together, 4 + 10 + 12 +7 + 8 + 3.

(The 8 and the 3 are apart of the sides that are not labeled. Since 12 - 4 = 8, and 10 - 7 = 3, That's where these numbers come from.)

Area - 4 * 10 = 40,

 +        8 * 7 =  56,

--------------------------------

                   = 96

I hope this helps :)

Answer 2

Answer:

Perimeter is 44cm

Area is 96cm²

Step-by-step explanation:

Perimeter=side+ side+side.....

●To find the missing horizontal side use the sides they give you :.the horizontal side will be 12-4 =8

●Do the same to find the missing vertical side:

10-7=3

:. Perimeter= 4+10+12+7+8+3

=44

(If you were to skip steps you could've also just seen it as 10+12+10+12=44)

To find area break the shape into manageable shapes you know the area formula of, like 2 rectangles. To help visualize it draw a line separating down from the 3cm vertical side we just calculated.

Area of rectangle 1 = length x breadth

=4×10

=40 units²

Area of rectangle 2 =length x breadth

=7×8

=56 units²

Therefore total area= rectangle 1 + rectangle 2

= 40 units²+ 56 units²

= 96 units²

Tip...to help when calculating do'nt be afraid to draw on the diagram and fill in the numbers you calculated previously to prevent confusion.
