Answer 1

(a) 88 m

(b) 74 cm

Step-by-step explanation:

You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.

(a) Perimeter

The perimeter of a rectangle is given by the formula ...

P = 2(L +W)

Filling in the given values, we can find the unknown.

330 = 2(L +77)

165 = L +77 . . . . . . . divide by 2

165 -77 = 88 = L

The length of the garden is 88 meters.

(b) Area

The area of a rectangle is given by the formula ...

A = LW

Filling in the given values, we can find the unknown.

6734 = 91W

6734/91 = 74 = W

The width of the window is 74 cm.

Answer 2

Answers:
(A):88
(B):74

Step-by-step explanation:

For (A), first multiply 77 by 2 then subtract from 330

77x2=154

330-154=176

For (A), second divide 176 by 2

176/2=88

Length=88

For (B), divide 6734 by 91

6734/91=74

Hope this helps!
