Answer:

Length 37 cm, width 25 cm.

Step-by-step explanation:

Let the original dimensions be length x and width x - 12 cms.

The new dimensions will be length (x - 2) and width (x - 12 - 2) = x-14 cm.

So , from the areas, we have:

x(x - 12) - (x - 2)(x - 14) = 120

x^2 - 12x - (x^2 - 16x + 28) = 120

-12x + 16x - 28 = 120

4x = 148

x = 37 cms

So the length was 37 cm and the width was 37-12 = 25 cm.

Solve the formula for b2. A=1/2h(b1+b2)

Katena32 [7]

Firstly, multiply both sides by 2: $2A=h(b_1+b_2)$

Next, divide both sides by h: $\frac{2A}{h}=b_1+b_2$

Next, subtract both sides by b1, and <u>your answer will be $\frac{2A}{h}-b_1=b_2$ </u>
