A rectangular department store, 80 m by 60 m is to be built on a city block having an area of 9000 m2. There is to be a uniform strip around the building for a lawn. How wide is the strip (to the nearest hundredth of a metre)?

1.true 2.false? ? i think. .

step-by-step explanation:

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.

i think the length is 12 and the width is 17
