Answer:
length = 30 feet and width = 20 feet
Step-by-step explanation:
Let l is length and b is width of a rectangular yard. The area of a rectangle is given by :
A = lb ..(1)
A rectangular yard has a length that is 10 feet longer than the width.
length, l = 10+b ...(2)
ATQ,
Put the value of l in equation (1),

Width can't be negative. The width is 20 feet.
Put the value of b is equation (2),
l = 10+20
l = 30 feet
Hence, the length and width are 30 feet and 20 feet.

Answer:
the areas of these triangles are 83.2cm² and 46.8cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:
4²:3²
16:9
2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:
130(16/16+9)
130(0.64)
=83.2cm²
3. The area of the smaller triangle is:
130(9/16+9)
130(0.36)
46.8cm²
