Work out the area of a rectangle with base, b = 16mm and perimeter, P = 50mm.

144mm^2

Step-by-step explanation:

16•2= 32

50-32= 18

18/2=9

9•16=144

144mm

Step-by-step explanation: The formula for perimeter is b+b+h+h therefore if you add 16+16 you get 32 then you subtract 50 by 32 leading to 18 then you divide this 18 by 2 which gives you 9. The formula for area is b times h so your equation is 16x9 which is equal to 144.

the monthly balance will be $75,000

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
