A triangle and a rectangle are equal in area.
The base of the triangle is 6.4 cm and Height is 5.7 cm.
if the length of the rectangle is 3.8 cm find its breadth.?
:
let w = the width of the rectangle
rect area = triangle area
3.8*w = 1%2F2*6.4*5.7
3.8w = 18.84
w = 18.84%2F3.8
w = 4.8 is width of the rectangle

Check this,
find the area of the rectangle: 4.8 * 3.8 = 18.24, the same as the triangle
