Answer:
Area of the square is 2916 .
Step-by-step explanation:
Let the breadth of the rectangle be represented by w. So that;
length of rectangle = 5w
Area of rectangle = length x breadth
= 5w x w
1620 = 5
divide through by 5 to have,
= 324
w =
= 18
Thus, the breadth of the rectangle is 18 m.
length = 5 w = 5 x 18
= 90 m
The length of the rectangle is 90 m.
Perimeter of the rectangle = 2(l + w)
= 2( 90 + 18)
= 216 m
Perimeter of a square = 4l
where l is the length of its side.
Given that the perimeters of the rectangle and square are equal, then;
4l = 216
l =
= 54
length of the side of square is 54 m.
Therefore,
Area of square =
=
= 2916
Area of the square whose perimeter is equal to that of the rectangle is 2916 .
Given:
The ratio of 45-45-90 triangle is .
The hypotenuse of the given isosceles right triangle is .
To find:
The lengths of the other two sides of the given isosceles right triangle.
Solution:
Let be the lengths of the other two sides of the given isosceles right triangle.
From the given information if is clear that he ratio of equal side and hypotenuse is . So,
Therefore, the lengths of the other two sides of the given isosceles right triangle are 7 units.
