Answer:
The answer is that Lara would need 9 pages to store all her photos.
Step-by-step explanation:
You would need to first divided 43 divided by 5 to get 8.6.
However, you can't have a tenth of a page so you would have to round to 9 so the answer is that Lara would need 9 pages to store all her photos.
Let's look at the formula to solve the perimeter.
2l+2w=98
We know that l=6w
Let's put that into the equation.
2(6w)+2w=98
12w+2w=98
14w=98
98÷14=7
So the width is 7. Let's find the length.
Since the length is six times the width: 7×6= 42
So, the length is 42 while the width is 7. We need to find the area.
42×7=294
The area is 294 m².

Answer:
1) 147
2) 87
Step-by-step explanation:
1) Area of triangle = × base length × height
=
× 14 × 10
= 70 
Area of a semicircle =
( r is the radius)
Radius = half of diameter =
= 7m
Area of semicircle = 
= 77
( Nearest whole number )
Total area = 77 + 70 = 147
2) Divide the shape into 2 rectangles
Area of a rectangle = length × width
Rectangle 1 = 7 × ( 3+3+5 )
= 7 × 11 = 77
Rectangle 2 = 2 × 5
= 10
Total Area = 77 + 10 = 87
