Lines AB and AC are equal so you set up an equation like so...
4x + 1 = 2x + 23
Subtract 1 from both sides.
4x = 2x + 22
Subtract 2x from both sides.
2x = 22
Divide.
x = 11
Now you need to plug in 11 into 3x - 8.
3(11) - 8
= 33 - 8
= 25
So BC is 25.

If length of rectangle is 8 cm, breadth is 4 cm, side of square is 3 cm, base of triangle is 3 cm, then the area of figure will be 48.5 
.
Given that length of rectangle is 8 cm, Breadth of rectangle is 4 cm,side of square is 3 cm,base of right angled triangle is 3 cm,height of triangle is 5 cm.
Area of figure=Area of rectangle+Area of square+Area of triangle
Area of rectangle=length*breadth
Area of square=Side*Side
Area of triangle=1/2 *Base*Height
Area of figure=8*4+3*3+1/2 *3*5
=32+9+1/2 *15
=41+15/2
=(82+15)/2
=97/2
=48.5
Hence if length of rectangle is 8 cm, breadth is 4 cm, side of square is 3 cm, base of triangle is 3 cm, then the area of figure will be 48.5 .

Note the place values:
9 ones place value
. (decimal point)
3 tenths place value
4 hundredths place value
8 thousandths place value
8 ten thousandths place value
You are solving for the tenth place value. Look at the digit directly right of the tenths place value. It is the hundredths place value, which is 4.
Note that when rounding, if the number next to what you are solving for, has a value of 5 or greater, you round up. If it has a value of 4 and less, you round down. In this case, it is a 4, so round down.
9.3488 rounded to the nearest tenth is 9.3
9.3 is your answer.
