Kiran has 10 1/2 feet of lumber and wants to make a bookshelfKiran needs two side panels that are each 5 2/3 feet. How much more

eimsori [14]

Total height of lumber, H = 10 1/2 feet = 21/2 feet .

Height of side panel, h = 5 2/3 feet = 17/3 feet .

Now,

Extra lumber required, L = 2 × Height of side panel - Total height of lumber

$L=[2\times (\dfrac{17}{3})]-\dfrac{21}{2}\\\\L = \dfrac{5}{6}\ feet$

Therefore, extra lumber required is $\dfrac{5}{6}$ feet.

Hence, this is the required solution.

A playing card has an area of 50 square centimeters and a perimeter of 30 centimeters. What are the dimensions of the playing ca

Reika [66]

The dimensions of playing card is L = 10 centimeter and W=5 centimeter, If the playing card has an area of 50 square centimeter and a perimeter of 30 centimeters.

Step-by-step explanation:

The given is,

Playing card has an area of 50 square centimeters

A perimeter of 30 centimeters

Step:1

A playing card is in the shape of rectangle,

Formula for perimeter of rectangle is,

$Perimeter, P = 2(l+w)$ .........................(1)

Formula for area of rectangle is,

$Area, A= lw$ ......................................(2)

Where, l - Length of rectangle

w - Width of rectangle

Step:2

From the given values equation (1) becomes,

$30 = 2(l+w)$

$\frac{30}{2}=(l+w)$

$15 =(l+w)$

$w=15-l$ .............................(3)

Width value in terms of length is calculated.

Step:2

Equation (2) becomes,

$50 = (15-l)(l)$

$50= 15l -l^{2}$

$l^{2}-15l+50=0$

Solving the above equation,

$=10$

$l=10 cm$

Step:3

Equation (3) becomes,

$w=15-l$

$=15-10$

$=5$

w = 5 cm

Result:

The dimensions of playing card is L = 10 centimeter and W = 5 centimeter, If the playing card has an area of 50 square centimeter and a perimeter of 30 centimeters.
