Question

The length of rectangle 4cm more than breadth area is 192 cmsq find the length and breadth?

Answer 1

Answer:

Area = 192 = (b)(b+4) …. b^2 + 4b -192 = 0 Use Quadratic Formula where a=1, b=4 and c=-192 —- b = -4 +/- SqRt(4^2 -4(1)(-192) where “b” = + 12 and -16.

The breath and depth of the rectangle are 12cm by 16cm
