Principal ( P ) = £ 1800
Rate ( R ) = 5%
Time ( T ) = 3 years

$\underline{ \underline{ \text{To \: find}}} :$

Total amount

$\underline{ \underline{ \text{Solution}}}:$

First , finding the amount of interest :

$\boxed{ \sf{Interest = \frac{PTR}{100}}}$

⇢ $\sf{Interest = \frac{1800 \times 5 \times 3}{100}}$

⇢ $\sf{Interest = \frac{27000}{100}}$

⇢ $\sf{Interest = £ 270}$

Now , Finding the total amount :

$\boxed {\sf{Total \: amount = Principal + Interest}}$

⇢ $\sf{Total \: amount = 1800 + 270}$

⇢ $\sf{Total \: amount = \: £ 2070}$

$\red{\boxed{ \boxed{ \tt{Our \: final \: answer : brian \: will \: have £ 2070 \: after \: 3 \: year.}}}}$

Solve the formula for the area of a triangle A = (1/2) bh for height h

Hitman42 [59]

A = (1/2) bh for height h

2A = bh

first multiply both sides by 2 then divide both sides by b

Area of triangle = (1/2)bh

A = (1/2)bh

2A = bh

h = 2A/b

110 = 1/2(11)h

110 = 5.5h

110/5.5 = 20

The answer Is H = 20

Hope this helps (:
