Please solve both with explanation

Step-by-step explanation:

area of rectangle=length*width

=17 cm*9 cm

=1323 cm^2

perimeter of rectangle=2(l+w)

=2(17+9)

=2*26

=52 cm

area of square=l^2

=12^2

=144 m^2

perimeter of sqaure=4l

=4*12

=48 m

see explanation

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = lb ( l is length, b is breadth )

The perimeter (P) is the sum of the 4 sides

(a)

A = 9 × 17 = 153 cm²

Since opposite sides are congruent, then

P = 2(9 + 17)

  = 2 × 26

  = 52 cm

(b)

A =  12 × 12 = 144 m²

P = 4 × 12 = 48 m

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
