Answer:-602

Step-by-step explanation:

First term=a=-143

common difference=d=-134-(-143)=9

Using the formula

Sn=n/2(2a+d(n-1))

S28=28/2 (2(-143)+9(28-1))

S28=14(-286+9x27)

S28=14(-286+243)

S28=14(-43)

S28=-602

the ratio of length and breadth of a piece of land is 5:3 and its breadth is 48m. find the perimeter and area of the land.
Marizza181 [45]

Answer:

256 m and 3840 m²

Step-by-step explanation:

The 3 part of the ratio represents 48 m , then

48m ÷ 3 = 16 m ← value of 1 part of the ratio, so

5 parts = 5 × 16 m = 80 m

Then breadth = 48 m and length = 80 m

perimeter = 2l + 2b = 2(80) + 2(48) = 160 + 96 = 256 m

area = lb = 80 × 48 = 3840 m²
