Answer:

The ratio of smaller rectangle to larger is 1 : 8.

Step-by-step explanation:

Given that:

Area of smaller rectangle = 25 square feet

Area of larger rectangle = 200 square feet

Ratio of areas of these similar rectangles;

Smaller rectangle : Larger rectangle

25 : 200

1 : 8

Hence,

The ratio of smaller rectangle to larger is 1 : 8.

A house number is displayed on a plaque in the shape of a regular 7-sided polygon. The area of the plaque is 70 squared inches.
Svetllana [295]

Answer:

The perimeter of the plaque is 28 inches.

Step-by-step explanation:

Given : A house number is displayed on a plaque in the shape of a regular 7-sided polygon. The area of the plaque is 70 squared inches. The perpendicular distance from a side to the center is 5 inches to the nearest inch.

To find : What is the perimeter of the plaque?

Solution :

The 7-sided polygon can be divided into seven triangles whose height, h is equal to the perpendicular distance from each side to the center.

The base of each triangle is equal to the length of a side, s.

The area of each triangle is A=\frac{1}{2}\times s\times h

The area of the whole polygon is A_p=\frac{1}{2}\times 7s\times h

Now, the perimeter of a regular 7-sided polygon is P=7s.

Substitute in area,

A_p=\frac{1}{2}\times P\times h

We have given, A_p=70\ in^2 and h=5\ in

70=\frac{1}{2}\times P\times 5

P=\frac{70\times 2}{5}

P=28

The perimeter of the plaque is 28 inches.

liubo4ka [24]

Answer:

960

Step-by-step explanation:

(if i made any typos, sorry it is kind of hard to type on computer over writing on paper.)

A=2AB+(a+b+c)h

AB=s(s﹣a)(s﹣b)(s﹣c)

s=(a+b+c)/2

Solving forA

A=ah+bh+ch+1/2 sqrt(﹣a^4+2(ab)^2+2(ac)^2﹣b4+2(bc)^2﹣c^4)=10·12+24·12+26·12+1

2·﹣104+2·(10·24)2+2·(10·26)2﹣244+2·(24·26)2﹣264=960
