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.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
