If the perimeter of the equilateral triangle is 18 cm then the width of the rectangle be 11.2 cm.

Given that the perimeter of the equilateral triangle be 18 cm and the perimeter of all the three triangles be 46.4 cm.

We are required to find the width of the rectangle.

Rectangle is basically the shape which is having opposite sides equal to each other.

Perimeter of equilateral triangle=3 *side

3* side=18

side=18/3

side=6

Since it is on the length of the rectangle so the length of rectangle be

6 cm.

Perimeter of all the three triangles=2*width of the rectangle+1 length+perimeter of 1 equilateral triangle.

T1 and T2 are the other triangles.

Suppose the width of the rectangle be x.

Perimeter=2*x+6+18

46.4=2x+24

2x=46.4-24

2x=22.4

x=11.2

So,the width of the rectangle is equal to 11.2 cm.

Hence if the perimeter of the equilateral triangle is 18 cm then the width of the rectangle be 11.2 cm.

Nat2105 [25]

Answer: -4x+5>-5=x>2.5

-25>-5(x+2.5)=x<2.5

Step-by-step explanation:

-4x+5>-5 -25>-5(x+2.5)

-5 -5 -25>-5x-12.5

-4x>-10 +12.5 +12.5

/-4 /-4 -12.5>-5x

x>2.5 /-5 /-5

2.5>x

x<2.5

How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? Or how are they different. Explai
Radda [10]

Answer:

They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.

In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.
