The perimeter of a rectangle is 24cm. If the length is 7cm, find the width.

perimeter of rectangle=2(l+b)

24cm = 2(7cm+w)

24cm =14cm+2w

24cm - 14cm = 2w

10cm=2w

10cm/2=w

5cm=width.

the perimeter of a rectangle = 2(l+b)

length = 7cm

2(7+b) = 24

7+b = 24/2 = 12

b=12-7 = 5

width = 5cm

hope this answer helps you...

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.
