The dimensions of a rectangular-shaped playground measure 2⋅10^2 centimeters long by 9⋅10^2 centimeters wide.

Find the approximate area of the playground.

Write your answer in scientific notation and round coefficients to the nearest tenth.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
