A rectangle has a width of 2/7 cm and a length represented by the expression a+4. Find the area. (tell me how btw! and i will give brainliest.)

we know the formula for area is,

L x W

so,

2/7 (a+4) = area

solve this by distributing the 2/7,

you get = 2/7a + 8/7

the area is 2/7a + 8/7

if correct, please mark the brainliest :)

Length = 13 = (x + 3)

Width = 14 = (x + 4)

x2 + 7x + 12 = area of the rectangle

can be factored into

(x + 3)(x + 4)

Let L = one of the factors (x + 3)

Let W = the other factor (x + 4)

If x = 10 then

(10 + 3) = 13 = L

(10 + 4) = 14 = W

Checking this can be checked a couple of ways

Plug x = 10 into the original equation

x2 + 7x + 12

102 + 7(10) 12 = 100 + 70 + 12 = 182 = Area

Multiplty the factors

L x W = 13 x 14 = 182 = Area
