Answer:

20 m²
21 m²
less than

Step-by-step explanation:

Trapezoid

The trapezoid has been broken into two triangles and a rectangle. The two triangles both have the same dimensions, so both have the area ...

A = (1/2)bh = (1/2)(2 m)(5 m) = 5 m²

The rectangle has area ...

A = bh = (2 m)(5 m) = 10 m²

So, the total area of the trapezoid is ...

trapezoid area = 5 m² +10 m² +5 m²

trapezoid area = 20 m²

Kite

The kite has been broken into two triangles, so the area of each of them is ...

A = (1/2)bh

A = (1/2)(7 m)(3 m) = (21/2) m²

Then the area of the two halves of the kite will be ...

kite area = 2 × (21/2 m²)

kite area = 21 m²

The area of the trapezoid is 1 m² less than the area of the kite.

The top and bottom faces are 3 inches by 3 inches.

Area = 3 in. * 3 in. * 2 = 18 in.^2

The front, back, right, and left faces are 3 in. by 6 in.

Area = 3 in. * 6 in. * 4 = 72 in.^2

Total surface area = 18 in.^2 + 72 in.^2 = 90 in.^2

bagirrra123 [75]

Given,

CP of cosmetics = Rs 360 per dozen

SP of a pair of cosmetics = Rs 80

To find,

The gain percent

Solution,

1 dozen = 12 items

CP of 1 cosmetic = 360/12 = Rs 30

SP of 1 cosmetic = 80/2 = Rs 40

Profit = SP-CP

= Rs 40 - Rs 30

= Rs 10

Profit percentage is given by :

$\%=\dfrac{profit}{CP}\times 100\\\\=\dfrac{10}{30}\times 100\\\\=33.34\%$

So, the profit percentage is 33.34%.
