A rectangle has a perimeter of 34 cm in an area of 52 cm squared it's length is 5 more than twice its width write and solve the
valina [46]

Let l be the length and w be the width of the rectangle.

Given perimeter of the rectangle

2(l+w)=34 \; l+w=17

Area of the rectangle is

lw=52

Also length is 5 more than twice its width,

l=2w+5

From the above equations

(l-w)^2=(l+w)^2-4lw=17^2-4*52=81\\ l-w=9,\; since \; l>w

Now 2l=9+17=26\;,l=13,w=4

The dimensions of the rectangle are length l=13, and width w=4.

Sarah sells fruit trays at a salad shop. Last week, she sold 450 fruit trays for $8 per tray. In previous weeks, she found that
Mamont248 [21]

Sarah's income = Number of trays × Rate per tray

y = 450 × 8

If there is an increase of 0.85 in price,

New price = 8 + 0.85

For x number of increases,

new price = 8 + 0.85x.

Number of trays reduced = 450 - 15x.

So, Sarah's income in this case is y = (450 - 15x) (8 + 0.85x).

Help me with this plsss
Brrunno [24]

1.

a. 8 x 7 x 1/2 = 56 x 1/2 = 28

b. 24 x 14 x 1/2 = 336 x 1/2 = 168

c. 5 x 12 x 1/2 = 60 x 1/2 = 30

d. 4 x 4.8 x 1/2 = 19.2 x 1/2 = 9.6

2.

two triangles: 2(4 x 8 x 1/2) = 4 x 8 = 32

rectangle: 15 x 8 = 120

total area: 32 + 120 = 152
