The ratio is: 7cm to 1cm
h
2.5:1 or 5:2
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
28cm is about 11 inches
It would be 64 cm3. So the unit is cm3
It is an equilateral triangle
28cm
28
Area= length x width. Therefore, Area= 7cm x 4cm=28cm squared.
2.5:1 or 5:2
The height of the trapezoid is also needed to find its area which is as follows:- Area of a trapezoid = 0.5*(sum of bases or parallel sides)*height
The ratio of their heights is 9:4
The area of rhombus with diagonals 28Cm square and 28Cm is: 392 cm2
The ratio of the circumference of a circle with radius 4 cm to its area is 1:2.
28cm is about 11 inches
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
It is: 2 to 3 respectively
28cm*22cm=616cm sq.
