Please state the width (part a)
And length (part b)

(a) = 71 cm

(b) = 89 cm

Step-by-step explanation:

(a.)

perimeter of a rectangular field = 324 m

length (l) = 91 m

width (w) = ?

Now,

Perimeter Of Rectangle

= P = 2(l + w)

= 2(91 + w) = 324m

= 182 + 2w = 324m

= 2w = 324 - 182m

= 2w = 142m

= w = 142/2

= w = 71

(b.)

area of rectangular painting = 5696 cm²

width (w) = 64 cm

length (l) = ?

Now,

Area Of Rectangle

A = l × w

= l × 64 = 5696

= l = 5696/64

= l = 89 cm

FOR (a)

= P = 2(l + w)

= P = 2(91 + 71) = 324 cm

FOR (b)

= l × w

A = 89 × 64 = 5696

answer: finding the extract measurements and knowing the points

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
