Answer:
12 cm x 15 cm
Step-by-step explanation:
if the picture frame thickness is x,
then the frame dimension would be (8+2x) cm by (11+2x) cm
area is (8+2x)(11+2x)=180
solve for x, x= 2, -23/2
x is thickness, so should be >0, so x=2
frame dimension: 12 x 16
5/8 * 300 = 1500/8 = 187.5 people

Answer:
(1)
Step-by-step explanation:
Given
+ b = c ( subtract b from both sides )
= c - b ( multiply both sides by a to clear the fraction )
2x = a(c - b) ← distribute
2x = ac - ab ( divide both sides by 2 )
x =
→ (1)
