Answer:

The length of one plot is 45m & the other length is 25m

Step-by-step explanation:

Let length one sq. plot = x length other sq. plot = y

area of square = length²

x² + y² = 2650 -----(1)

x² - y² = 1400 ------(2)

(1)+(2)

2x² = 4050

x² = 2025

x = 45

subx²=2025into(1)

2025 + y² = 2650

y² = 625

y = 25

Alekssandra [29.7K]

Answer:

$7,012.76

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 7/100

r = 0.07 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 5,000.00(1 + 0.07/1)(1)(5)

A = 5,000.00(1 + 0.07)(5)

A = $7,012.76

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $5,000.00 at a rate of 7% per year compounded 1 times per year over 5 years is $7,012.76.
